Abstract: Nanosized cerium oxide (CeO2) particles were prepared by co-precipitation method using chitosan as a template, cerium (III) nitrate and cerium (IV) sulfate as starting materials and aqueous ammonia solution as a precipitating agent. XRD data indicate that cerianite with face-centered cubic phase is formed in the reaction systems. The size of the coherent scattering regions is about 3 nm or less. FTIR spectroscopy data indicate the interaction of polymer molecules with the inorganic component. The shift of absorption bands related to N-H bonds for composites with Ce(III) and Ce(IV) compared to chitosan indicates the interaction of amino groups with CeO2 particles. The application of chitosan as a matrix for the synthesis of CeO2 nanoparticles showed that this approach is more economical and easier to produce nanomaterials for various applications.
